现在，我在'res/layout'文件夹内存储每个XML布局文件，因此管理小型项目是可行和简单的，但当有大型和繁重的项目的情况下，那么应该有一个层次结构和子文件夹内需要的布局文件夹。
如。
layout
-- layout_personal
-- personal_detail.xml
-- personal_other.xml
--layout_address
-- address1.xml
-- address2.xml
同样，我们希望大型应用程序有子文件夹，那么在Android项目中有办法做到这一点吗?
我能够在布局文件夹内创建layout-personal和layout_address子文件夹，但当需要使用R.layout访问XML布局文件时。_______，当时在菜单中没有任何XML布局弹出。

答案是否定的。
我想提请您注意这本书Pro Android 2，它指出:
It is also worth noting a few constraints regarding resources. First, Android supports only a linear list of files within the predefined folders under res. For example, it does not support nested folders under the layout folder (or the other folders under res). Second, there are some similarities between the assets folder and the raw folder under res. Both folders can contain raw files, but the files within raw are considered resources and the files within assets are not. Note that because the contents of the assets folder are not considered resources, you can put an arbitrary hierarchy of folders and files within it.

现在有了Android Studio和Gradle，你可以在你的项目中有多个资源文件夹。允许组织不仅你的布局文件，但任何类型的资源。
它不是一个确切的子文件夹，但可以分离应用程序的部分。
配置如下:
sourceSets {
main {
res.srcDirs = ['src/main/res', 'src/main/res2']
}
}
检查文档。
我使用Android文件分组插件的Android工作室。它不允许你创建子文件夹，但是它可以显示你的文件和资源，因为它们在不同的文件夹中。这正是我想要的。
你可以安装“Android文件分组”插件通过
窗口:
Android Studio ->文件->设置->插件。
Mac:
Android Studio标签(左上)->首选项->插件->安装JetBrains插件..
对于Mac，我能够测试它，不能搜索插件。所以我从这里下载了插件，并从上面的设置中使用了从磁盘安装插件选项。
I think the most elegant solution to this problem (given that subfolders are not allowed) is to prepend the file names with the name of the folder you would have placed it inside of. For example, if you have a bunch of layouts for an Activity, Fragment, or just general view called "places" then you should just prepend it with places_my_layout_name. At least this solves the problem of organizing them in a way that they are easier to find within the IDE. It's not the most awesome solution, but it's better than nothing.
如果你是在linux或mac上开发，一种变通方法是，创建包含符号链接到布局文件的子文件夹。只需使用ln命令和-s
ln -s PATH_TO_YOUR_FILE
问题是，你的布局文件夹仍然包含所有的.xml文件。但是你可以通过使用子文件夹来选择它们。这是最接近你想要的东西。
我刚读到，如果你使用的是Vista或更高版本，这可能也适用于Windows。这里有一个mklink命令。只是谷歌，我从来没用过。
另一个问题是，如果你已经打开了文件，并试图再次打开它，插件抛出一个空指针异常。但它并没有挂断。
